Description
1 . APPARATUS FOR MIXING A FLUID AND A LIQUID
3 The invention relates to apparatus for introducing a fluid 4 into a first liquid and especially a container which introduces the fluid into the first liquid on opening of 6 the container.
8 In a wide number of applications, such as pharmaceuticals 9 for both human and animal use, agrochemicals and other more general applications it may be necessary to release 11 and mix a liquid catalyst or reagent into a liquid before 12 the liquid may be used. Conventional methods involve a 13 user measuring out the liquid catalyst or reagent and then 14 adding it to the main liquid. This may cause problems in that it is prone to human error in the measuring of the 16 amount of liquid catalyst or reagent and may also be 17 hazardous if the catalyst or reagent is toxic.
19 In accordance with the present invention, apparatus for introducing a fluid into a first liquid comprises a first 21 container for containing the first liquid, the first 22 container having an opening closed by a releasable 23 closure, and a second container located in the first 24 container adjacent the opening of the first container; the second container comprising an outer housing located in 26 the opening and an inner Container containing a fluid, the 27 inner container including a rupturable member and being 28 movably mounted in the housing for movement between a 29 closed position in which the inner container is sealed by the housing when the releasable closure closes the 31 opening, and an open position in which the fluid within 32 the inner container is released from the inner container 1 into the first container and into contact with the first 2 liquid on release of the releasable closure, the housing 3 also including a rupturing member to rupture the 4 rupturable member on the inner container.
6. An advantage of the invention is that by using a second 7 container located adjacent the opening of the first 8 container and adapted to release a fluid into the first 9 container and into contact with the first liquid on release of the closure, it is possible to introduce the 11 fluid into the first liquid without requiring direct 12 handling of the fluid by a user.
14 Preferably, the second container may include a conduit into which the fluid passes on release of the closure and 16 the conduit extends below the surface of the first liquid 17 in the first container. Typically, the conduit extends to 18 at least adjacent the mid-section of the first liquid in 19 the first container and preferably, extends to adjacent the bottom of the first container.
22 Typically, the fluid may be a gas and/or a second liquid.
23 The fluid may be pressurised to aid expulsion of the fluid 24 from the second container on release of the closure.
Typically, where the second container comprises an outer 26 housing and an inner container, pressurised gas is located 27 in the inner container with the second liquid.
1 Preferably, the inner container includes a rupturable 2 member and the housing includes a rupturing member to 3 rupture the rupturable member on the inner container.
4 Typically, the rupturable member may be a membrane.
6 Preferably, the inner container is located in an 7 initial position prior to insertion into the container 8 and on closing of the first container by the closure 9 moves the inner container to the closed position.
Typically, the second container also includes a sealing 11 device and when the inner container is in the closed 12 position the rupturing member has ruptured the 13 rupturable member of the inner container but the 14 contents of the inner container are prevented from being released from the inner container by the sealing 16 member. Typically, the sealing member is attached to 17 the inner container and seals against the rupturing 18 member on the housing. When the inner container moves 19 to the open position the seal member no longer prevents release of the fluid from the inner container.
22 Preferably, the first and second liquids may be any 23 combination of liquids. Examples of first and second 24 liquids are pharmaceutical liquids, agrochemical liquids and any other combination of liquids which 26 requires a second liquid to be added to a first liquid 27 prior to use of the liquid mixture.
29 An example of a container for introducing a fluid into a first liquid in accordance with the invention will 31 now be described with reference to the accompanying 32 drawings, in which:-i 34 Fig. 1 is a cross-sectional view of a first example of a second container in a shipping or 36 storage position;
1 Fig. 2 is a cross-sectional view of the second 2 container of Fig. 1 showing the position of the 3 second container when located in a first container 4 and the first container opening is closed;
Fig. 3 is a cross-sectional view of the second 6 container of Fig. 1 showing the position of the 7 second container when the closure on the first 8 container is released;
9 Fig. 4 is a cross-sectional view of a second example of a second container when located in a 11 first container and the first container opening is 12 closed; and 13 Fig. 5 is a cross-sectional view through an outer 14 housing for a third example of a second container.
16 Fig. 1 shows a second container 20 which comprises an 17 outer housing 1 which has an upper lip 2. Extending 18 from the bottom of the housing 1 is a dip tube 19 connector 5. The housing 1 has a rupturing member 6 which extends upwards and terminates in a spike 7. A
21 dip tube (not shown) may be attached to the connector 22 5, if desired.
24 In the side wall of the housing 1 is a ridge 3 which extends circumferentially around the inside of the 26 housing 1.
28 An inner container 11 has a lower open end which is 29 sealed by a sealing gasket 12 and a rupturable membrane 13. The gasket 12 is annular and defines a central 31 aperture 14. The container 11 also has an O-ring seal 32 8 encircling it in a circumferential recess 4 in the 33 container 11.
In use, the inner container 11 is filled with a liquid 36 15 and a pressurised gas 16 by means of conventional 1 technology used to fill pressurised dispenser packs, 2 commonly known as aerosol containers. The inner 3 container 1l is then inserted into the outer housing 1 4 and pushed into the outer housing 1 until the O-ring 8 5 engages with the ridge 3. This position is h s own in 6 Fig. 1. In this position the membrane 13 is above the 7 member 6 and spike 7.
8 In a wide number of applications, such as pharmaceuticals 9 for both human and animal use, agrochemicals and other more general applications it may be necessary to release 11 and mix a liquid catalyst or reagent into a liquid before 12 the liquid may be used. Conventional methods involve a 13 user measuring out the liquid catalyst or reagent and then 14 adding it to the main liquid. This may cause problems in that it is prone to human error in the measuring of the 16 amount of liquid catalyst or reagent and may also be 17 hazardous if the catalyst or reagent is toxic.
19 In accordance with the present invention, apparatus for introducing a fluid into a first liquid comprises a first 21 container for containing the first liquid, the first 22 container having an opening closed by a releasable 23 closure, and a second container located in the first 24 container adjacent the opening of the first container; the second container comprising an outer housing located in 26 the opening and an inner Container containing a fluid, the 27 inner container including a rupturable member and being 28 movably mounted in the housing for movement between a 29 closed position in which the inner container is sealed by the housing when the releasable closure closes the 31 opening, and an open position in which the fluid within 32 the inner container is released from the inner container 1 into the first container and into contact with the first 2 liquid on release of the releasable closure, the housing 3 also including a rupturing member to rupture the 4 rupturable member on the inner container.
6. An advantage of the invention is that by using a second 7 container located adjacent the opening of the first 8 container and adapted to release a fluid into the first 9 container and into contact with the first liquid on release of the closure, it is possible to introduce the 11 fluid into the first liquid without requiring direct 12 handling of the fluid by a user.
14 Preferably, the second container may include a conduit into which the fluid passes on release of the closure and 16 the conduit extends below the surface of the first liquid 17 in the first container. Typically, the conduit extends to 18 at least adjacent the mid-section of the first liquid in 19 the first container and preferably, extends to adjacent the bottom of the first container.
22 Typically, the fluid may be a gas and/or a second liquid.
23 The fluid may be pressurised to aid expulsion of the fluid 24 from the second container on release of the closure.
Typically, where the second container comprises an outer 26 housing and an inner container, pressurised gas is located 27 in the inner container with the second liquid.
1 Preferably, the inner container includes a rupturable 2 member and the housing includes a rupturing member to 3 rupture the rupturable member on the inner container.
4 Typically, the rupturable member may be a membrane.
6 Preferably, the inner container is located in an 7 initial position prior to insertion into the container 8 and on closing of the first container by the closure 9 moves the inner container to the closed position.
Typically, the second container also includes a sealing 11 device and when the inner container is in the closed 12 position the rupturing member has ruptured the 13 rupturable member of the inner container but the 14 contents of the inner container are prevented from being released from the inner container by the sealing 16 member. Typically, the sealing member is attached to 17 the inner container and seals against the rupturing 18 member on the housing. When the inner container moves 19 to the open position the seal member no longer prevents release of the fluid from the inner container.
22 Preferably, the first and second liquids may be any 23 combination of liquids. Examples of first and second 24 liquids are pharmaceutical liquids, agrochemical liquids and any other combination of liquids which 26 requires a second liquid to be added to a first liquid 27 prior to use of the liquid mixture.
29 An example of a container for introducing a fluid into a first liquid in accordance with the invention will 31 now be described with reference to the accompanying 32 drawings, in which:-i 34 Fig. 1 is a cross-sectional view of a first example of a second container in a shipping or 36 storage position;
1 Fig. 2 is a cross-sectional view of the second 2 container of Fig. 1 showing the position of the 3 second container when located in a first container 4 and the first container opening is closed;
Fig. 3 is a cross-sectional view of the second 6 container of Fig. 1 showing the position of the 7 second container when the closure on the first 8 container is released;
9 Fig. 4 is a cross-sectional view of a second example of a second container when located in a 11 first container and the first container opening is 12 closed; and 13 Fig. 5 is a cross-sectional view through an outer 14 housing for a third example of a second container.
16 Fig. 1 shows a second container 20 which comprises an 17 outer housing 1 which has an upper lip 2. Extending 18 from the bottom of the housing 1 is a dip tube 19 connector 5. The housing 1 has a rupturing member 6 which extends upwards and terminates in a spike 7. A
21 dip tube (not shown) may be attached to the connector 22 5, if desired.
24 In the side wall of the housing 1 is a ridge 3 which extends circumferentially around the inside of the 26 housing 1.
28 An inner container 11 has a lower open end which is 29 sealed by a sealing gasket 12 and a rupturable membrane 13. The gasket 12 is annular and defines a central 31 aperture 14. The container 11 also has an O-ring seal 32 8 encircling it in a circumferential recess 4 in the 33 container 11.
In use, the inner container 11 is filled with a liquid 36 15 and a pressurised gas 16 by means of conventional 1 technology used to fill pressurised dispenser packs, 2 commonly known as aerosol containers. The inner 3 container 1l is then inserted into the outer housing 1 4 and pushed into the outer housing 1 until the O-ring 8 5 engages with the ridge 3. This position is h s own in 6 Fig. 1. In this position the membrane 13 is above the 7 member 6 and spike 7.
9 The outer housing 1 and the inner container 11 are then inserted into the opening of a container, the outer 11 housing 1 fits inside the opening and the dip tube (if 12 fitted) extends into a first liquid in the container.
13 The outer housing 1 is supported in the opening by the 14 upper lip 2 which rests on the top of the opening. A
closure such as a threaded cap is then applied to the 16 container to close the container. On application of 17 the closure to the first container, the inner container 18 11 is moved downwards and moves to the position shown 19 in Fig. 2. An adhesive section may be provided on the top end of the container 11 and serves to attach the 21 top end of the container 11 to the inside of the 22 closure when the closure is applied to the container.
24 When the closure is applied to the first container, the inner container 11 moves to the position shown in Fig.
26 2. When this happens, the spike 7 bursts the 27 rupturable membrane 13 and the member 6 extends into 28 the aperture 14 in the gasket 12. In this position the 29 liquid 15 and gas 16 are prevented from escaping from the inner container 11 by the gasket 12 and member 6 31 which seal against each other to prevent release of the 32 liquid 15 and gas 16 from the container 11.
z 34 The inner container 11 remains in the position shown in Fig. 2 until a user releases the closure from the first 36 container. When this occurs, the inner container 11 1 moves to the position shown in Fig. 3. In this position the 2 gasket 12 becomes unsealed from the member 6 and liquid 15 3 is forced out of the container 11 by the pressurised gas 16 4 in the direction of arrows 17 and into the dip tube connector 5. The liquid 15 then passes through the dip tube 6 connector 5 and into the first liquid in the first 7 container, via the dip tube if fitted. On removal of the 8 closure, the housing 1, inner container 11 and dip tube o f 9 fitted) are removed from the first container because the inner container 11 is attached to the closure by adhesive.
11 The liquid 15 enters the first liquid through the dip tube 12 connector 5 and dip tube (if fitted) before the housing 1, 13 inner container 11 and dip tube (if fitted) are removed from 14 the first container. Liquid is prevented from passing up between the housing 1 and the inner containers 11 by the 0-16 ring 8.
18 It is possible that upward movement of the container 11 from 19 the position shown in Fig. 2 to the position shown in Fig. 3 could be aided by a spring located between the gasket 12 and 21 the bottom of the outer housing 1.
23 Hence, the container 11 may move to the position shown in 24 Fig. 3 by use of a spring and/or by means of the pressure within the container 11 which reacts against the member 6 to 26 push the inner container 10 to the position shown in Fig. 3.

28 A second example of a second container 30 is shown in Fig.
29 4. In the container 30, an inner container 41 is similar to the container 11 shown in Figs. 1 to 3 and also has an 0-31 ring 8. The main difference is that recess 42 is extended 32 compared to the recess 4 in inner container 11.
1 However, outer housing 31 is different to the outer 2 housing 1. The housing 31 comprises an upper lip 32 3 which is connected to a lower portion 33 by arm 4 portions 34. The lower ends of arm portions 34 form protruding nibs 35 which engage in the recess 42. Over 6 the end of the lower portion 33 is a dip tube adaptor 7 36 which has a connector 37 to which a dip tube may be 8 fitted, if desired. The adaptor 36 may be secured to 9 the lower portion 33 by glue or by a snap connection.
11 In use, the second container 30 operates and is used in 12 a similar manner to the second container 20. The 13 adaptor 36 directs the liquid 15 as it flows out of the 14 inner container 41 into the liquid in the first container, via the dip tube if fitted.
17 An example of a modified outer housing 50 is shown in 18 Fig. 5. The outer housing 50 is similar to the outer 19 housings 1, 31. The main differences are that there is a central portion 51 which has a recessed hollow 21 section 52 which communicates with side ports 53. On 22 the edge of the portion 51 is a spike 54.
24 In use, the outer housing 50 operates in a similar manner to the outer housings 1, 31 except that when an 26 inner container, such as the inner container 41 or the 27 inner container 11, is pushed onto the central portion 28 51, the sealing gasket 12 of the inner container seals 29 against the outside of the ports 53 and subsequent to this, the spike 54 punctures the membrane 13. Hence, 31 when the inner container is in a position similar to 32 the position shown in Figs. 2 and 4, the membrane 13 is 33 ruptured but ports 53 are sealed by gasket 12 to 34 prevent fluid from inside the inner container escaping from the inner container. When the cap on the first 36 container is removed, the inner container will move to 1 a similar position to that shown in Fig. 3. This will 2 result in the gasket 12 uncovering ports 53 and fluid 3 from inside the inner container will flow out of the 4 inner container through ports 53 which direct the fluid into the main body of the first container.
6 ' 7 The outer housing 50 has the advantage that it directs 8 fluid from the inner container into the main body of 9 the first container and onto the surface of liquid contents in the first container.
12 In the examples described above, the inner containers 13 may be secured to the cap of the first container, for 14 example, by putting blown polyethylene foam on the upper end of the inner containers and welding the blown 16 polyethylene foam to blown polyethylene foam on the 17 inside top of the cap of the first container by 18 ultrasonic welding. Other possibilities include 19 friction fitting the inner container to a hollow cap which is then secured to the inside of the cap of the 21 first container.
23 Modifications and improvements may be incorporated 24 without departing from the scope of the invention.
E
13 The outer housing 1 is supported in the opening by the 14 upper lip 2 which rests on the top of the opening. A
closure such as a threaded cap is then applied to the 16 container to close the container. On application of 17 the closure to the first container, the inner container 18 11 is moved downwards and moves to the position shown 19 in Fig. 2. An adhesive section may be provided on the top end of the container 11 and serves to attach the 21 top end of the container 11 to the inside of the 22 closure when the closure is applied to the container.
24 When the closure is applied to the first container, the inner container 11 moves to the position shown in Fig.
26 2. When this happens, the spike 7 bursts the 27 rupturable membrane 13 and the member 6 extends into 28 the aperture 14 in the gasket 12. In this position the 29 liquid 15 and gas 16 are prevented from escaping from the inner container 11 by the gasket 12 and member 6 31 which seal against each other to prevent release of the 32 liquid 15 and gas 16 from the container 11.
z 34 The inner container 11 remains in the position shown in Fig. 2 until a user releases the closure from the first 36 container. When this occurs, the inner container 11 1 moves to the position shown in Fig. 3. In this position the 2 gasket 12 becomes unsealed from the member 6 and liquid 15 3 is forced out of the container 11 by the pressurised gas 16 4 in the direction of arrows 17 and into the dip tube connector 5. The liquid 15 then passes through the dip tube 6 connector 5 and into the first liquid in the first 7 container, via the dip tube if fitted. On removal of the 8 closure, the housing 1, inner container 11 and dip tube o f 9 fitted) are removed from the first container because the inner container 11 is attached to the closure by adhesive.
11 The liquid 15 enters the first liquid through the dip tube 12 connector 5 and dip tube (if fitted) before the housing 1, 13 inner container 11 and dip tube (if fitted) are removed from 14 the first container. Liquid is prevented from passing up between the housing 1 and the inner containers 11 by the 0-16 ring 8.
18 It is possible that upward movement of the container 11 from 19 the position shown in Fig. 2 to the position shown in Fig. 3 could be aided by a spring located between the gasket 12 and 21 the bottom of the outer housing 1.
23 Hence, the container 11 may move to the position shown in 24 Fig. 3 by use of a spring and/or by means of the pressure within the container 11 which reacts against the member 6 to 26 push the inner container 10 to the position shown in Fig. 3.

28 A second example of a second container 30 is shown in Fig.
29 4. In the container 30, an inner container 41 is similar to the container 11 shown in Figs. 1 to 3 and also has an 0-31 ring 8. The main difference is that recess 42 is extended 32 compared to the recess 4 in inner container 11.
1 However, outer housing 31 is different to the outer 2 housing 1. The housing 31 comprises an upper lip 32 3 which is connected to a lower portion 33 by arm 4 portions 34. The lower ends of arm portions 34 form protruding nibs 35 which engage in the recess 42. Over 6 the end of the lower portion 33 is a dip tube adaptor 7 36 which has a connector 37 to which a dip tube may be 8 fitted, if desired. The adaptor 36 may be secured to 9 the lower portion 33 by glue or by a snap connection.
11 In use, the second container 30 operates and is used in 12 a similar manner to the second container 20. The 13 adaptor 36 directs the liquid 15 as it flows out of the 14 inner container 41 into the liquid in the first container, via the dip tube if fitted.
17 An example of a modified outer housing 50 is shown in 18 Fig. 5. The outer housing 50 is similar to the outer 19 housings 1, 31. The main differences are that there is a central portion 51 which has a recessed hollow 21 section 52 which communicates with side ports 53. On 22 the edge of the portion 51 is a spike 54.
24 In use, the outer housing 50 operates in a similar manner to the outer housings 1, 31 except that when an 26 inner container, such as the inner container 41 or the 27 inner container 11, is pushed onto the central portion 28 51, the sealing gasket 12 of the inner container seals 29 against the outside of the ports 53 and subsequent to this, the spike 54 punctures the membrane 13. Hence, 31 when the inner container is in a position similar to 32 the position shown in Figs. 2 and 4, the membrane 13 is 33 ruptured but ports 53 are sealed by gasket 12 to 34 prevent fluid from inside the inner container escaping from the inner container. When the cap on the first 36 container is removed, the inner container will move to 1 a similar position to that shown in Fig. 3. This will 2 result in the gasket 12 uncovering ports 53 and fluid 3 from inside the inner container will flow out of the 4 inner container through ports 53 which direct the fluid into the main body of the first container.
6 ' 7 The outer housing 50 has the advantage that it directs 8 fluid from the inner container into the main body of 9 the first container and onto the surface of liquid contents in the first container.
12 In the examples described above, the inner containers 13 may be secured to the cap of the first container, for 14 example, by putting blown polyethylene foam on the upper end of the inner containers and welding the blown 16 polyethylene foam to blown polyethylene foam on the 17 inside top of the cap of the first container by 18 ultrasonic welding. Other possibilities include 19 friction fitting the inner container to a hollow cap which is then secured to the inside of the cap of the 21 first container.
23 Modifications and improvements may be incorporated 24 without departing from the scope of the invention.
